Abstract

Human beta-defensin-2 (hBD-2), a small cationic peptide, exhibits a broad range of antimicrobial activity. It has been found to play important roles in innate and adaptive immune responses against microbial invasion. For the purposes of this study, hBD-2 gene was cloned from the lesions of human condyloma acuminatum. An expression vector was constructed and transformed into E. coli. hBD-2 was expressed as a fusion protein in both the soluble and insoluble forms, which was further confirmed by western blotting analysis.
